ADXL345 problems: no data

Hello! I'm new with arduino and have some problems with the ADXL345 accelerometer: It only delivers 0 0 0 for x y z.

I tried several tutorials like http://www.babelduck.com/index.php/en/reference/user-manuals/1427-adxl345-3-axis-accelerometer-sensor-module-product-manual and http://bildr.org/2011/03/adxl345-arduino/ but with all of these my accelerometer seems to deliver only nulls...
I wired it up exactly like in the manuals.

It's brand new and it's hard to believe, that it's broken. Wiring was always like it should.

Anyone an idea?

Thank you so much!

Just to check: you have an Arduino UNO as used in the tutorials?

You should start with the i2c_scanner, to see if the device is detected : Arduino Playground - I2cScanner

Oh, that's really awkward... I've a Mega and didn't know that there I've to use other pins.

Sorry for that, I'm just a beginner. So thank you very much, now it runs like a charme!
